Active vibrating model of a person sitting down for imitating a person's direct impedance against a seat includes a seat back contacting a back-plate on a base connected to a base-plate by a back joint.

摘要

A vibrating model (1) imitates a person's direct impedance against a seat (2). The seat has a seat back (3) contacting a back-plate (25) on a base that is connected to a base-plate (5) by a back knuckle joint (26). The vibrating model has a base (4) formed by the base-plate connected to a backing (7). The base-plate has a supporting surface (8) simulating a person's buttocks. The back-plate has a supporting surface (27) simulating the shape of a person's back.
